| Abstract: |
This invention relates to a deck or work platform of improved design supported so that it can be moved into a selected direction over the ground, both under water and on land. It may be used on the sea bottom, particularly at an offshore location and it may also be used on tundra, muskeg, swampy locations and the like. The improved tower of the present invention has combined mechanical and hydraulic support means and normally the hydraulic means would be used when moving the tower from one place to another while the mechanical support means would ordinarily be used after the tower was in a desired location.
